Counter-Strike: 1WIN vs Butterfly (BO3) - CCT Europe Series #5 Playoffs

Platform comparison

Market context

1WIN against Butterfly in the CCT Europe Series #5 playoffs is priced close to a coin flip, with the market at **51% YES** for 1WIN. That is broadly in line with the wider view: Kalshi has 1WIN around **53%** and Butterfly at **47%**, while bo3.gg’s pre-match ratings also have 1WIN as the slight favourite at 1.733 versus 1.938 for Butterfly.[14][1] In handicapper terms, consensus sits with 1WIN, but only marginally, so the value case is not an obvious favourite steam; it is more a question of whether the small edge on the listed favourite is already fully reflected.

The comparable tournament context matters because this is a best-of-three Round of 16 in a single-elimination playoff bracket, which usually reduces the role of one-map variance versus a one-map market.[3][4] Butterfly have already shown they can close out series in this event, including a 2-0 win over Benched gods in the group stage, while 1WIN also have prior positive playoff results in CCT-format competition, so neither side comes in as an overwhelming outlier.[8][7] The market’s near-even pricing suggests traders are treating this as a spot where veto order, map pool, and who lands the cleaner start may matter more than headline name value.

The main catalysts are operational rather than structural: whether the match starts on schedule, whether the bracket timing holds, and whether there is any late roster or admin change before the bo3 goes live. Liquipedia lists the playoffs as running from **30 July to 2 August** in a single-elimination bo3 format, and match pages place this fixture on 30 July, so the key risk for settlement is delay or rescheduling rather than format ambiguity.[3][1][2] If there is a late postponement beyond the market’s seven-day window, or the match is not completed cleanly, that would push the outcome towards the market’s special 50-50 rules rather than a straightforward team result.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
